On 8 February 1940, the 5./7 IAP (15 pilot led by kapitan A. Ye. Mol’bin) arrived from 18 IAP of Far East Army Corps (DVK) after a departure on 26 January to take part in the Finnish-Soviet Winter War. Later also personnel of 70 IAP and 22 IAP (which both had fought in the Khalkhin Gol-incident in August 1939) arrived.
Kapitan Mol’bin was shot down by AA-fire at Tikkola and killed on 14 February, when escorting SB-bombers. Starshiy leitenant Iosef Geibo took over 5./7 IAP, which received I-153s from 17 February.

On 8 March Finnish Blenheims from LeR 4 kept hammering the Soviet troops at the Gulf of Vyborg on 14 bombing missions while the fighters of LLv 24 flew 19 strafing missions. No Finnish aircraft were lost during the day.
It seems that the fighters from 7 IAP continued to intercept the Finnish aircraft and they claimed four Blenheims during the day.
Komissar Nikolay Antonov, major Iosef Khotelev and Pavlov (I-16s) claimed one Blenheim.
Georgiy Glotov and mladshiy leitenant Nikolay Ivanov of 3./7 IAP (I-153) claimed one Blenheim each.
Il’ya Kaynov, Yevgeniy Petrov and leitenant Romanov of 5./7 IAP (I-153) claimed a shared Blenheim.

Romanov was wounded on 10 March.

Romanov ended the war with 1 shared biplane victory.
